Dealing With JVM Limitations in Apache Cassandra
A couple of most notable NoSQL databases targeting large scalable systems are written in Java: Cassandra, HBase, BigCouch. Then there’s also Hadoop. Plus a series of caching and data grid solutions like Terracotta, Gigaspaces. They are all facing the same challenge: tuning the JVM garbage collector for predictable latency and throughput. Jonathan Ellis’s slides presented at Fosdem 2012 are coverin

Automating Hadoop/HBase deployments with Puppet
The guys from the Adobe SaaS team — same guys that shared with us their experience and reasons for using HBase — have ☞ open sourced their Puppet[1] recipes for automating Hadoop/HBase deployments. Right now we are open-sourcing on GitHub, Puppet recipes for: creating the user under which the entire hstack runs.changing system settings, like the ssh keys, authorizing machines to talk to each other
